[audio]w.x - Transmigration [sml020] - w.x
"Transmigration" was forged by two main concepts: nature and change. They both go hand in hand. Nature is constantly changing. Human beings, being a part of nature, are also constantly changing. Sometimes we do not have a say in what changes in our lives. There are times where we can uproot and take our troubles to another world and start all over. Though we can’t control every aspect of our lives, we ultimately change because of the decisions we have made...

[audio]w.x - Certain Species [SML019] - w.x
“Certain Species” is the opening track from my next album, "Transmigration", set to be released 08 September. This song is an homage to the migratory patterns of animals. Only certain species migrate every year and some migrate continuously their entire lives. There are many perils and struggles on this path but it is what makes them unique on this planet. The atmospheric tones and revolving patterns reflect the circular process of our existence and how it is our nature to do what we do...

[audio]Spontaneous Evolution - w.x
After taking a break from music a going back through my old catalog, I started to gain a sense of the true nature of my music. It is an intense tidal wave crashing down on the shores. It requires endurance and commitment. In an effort to branch out of this dark and depressing box I wanted to go a different direction. Drones and electronic tremors still fluctuate but in a softer vein, more soothing to the soul...

[audio]Incapacitation - w,x
This album's droning textures create a catatonic atmosphere, expressing the bleakness that this world sometimes shows us. Its tones submerge you into a dark environment where things can be frightening and it can feel like all hope is lost. Through each song this world becomes more like reality and acceptance sets in, forcing into your mind the idea that nothing is lost; it is merely traveling at a different pace than you...

[audio]Cure For Deafness - w.x
Noise. Harsh, aggressive, ear-splitting dog howling noise. These songs were created either from pure raw emotions or very wayward experimentation. There are layers upon layers of distortion on top of mutilated synthesizer tracks. The goal was to emulate the true feelings of some of mankind's more untamed emotions, such as hatred, rage and animosity. At times hearing these emotions played out can be unbearable but they are meant to expose the true beast in all of us.

[audio]Densitometry - w.x
Densitometry is made up of 9 songs that are spread out onto 11 tracks. This album is a statement against confining songs into the strict beginning and end of a track. Some songs are split into two tracks with a new song starting on the second track. Other songs are cut in half and are separated from each other by other songs. The music itself is a series of soundscapes crafted with ambient drones and minor distortion...

[audio]Manipulate [Ambient] - w.x
Manipulate [Ambient] continues the experimentation of Manipulate [Sound] with the utmost experimentation of sound. This time it specifically surrounds the ambient genre. The same effects manipulations and parameter automation were used for this project as before, just with more reverb and delay added. This paved the way for the drone projects I would do later on in 2007. http://sethmol.wordpress.com/2010/11/30/sml004-w-x-manipulate-ambient/

"Hailstone" is a reflection on weather and nature. By taking the darker aspects of weather and combining them with a subtle organic optimism, w.x has created an environmental journey that tears down our cynical views of life. Drenched with delays and drones, this is an atmospheric treat for the masses. This will be the last release under the "w.x" name. Keep in touch as bigger and better things are on the horizon...

[texts]Renormalization Group Analysis of the 2000-2002 anti-bubble in the US S&P 500 index: Explanation of the hierarchy of 5 crashes and Prediction - W. -X. Zhou
We propose a straightforward extension of our previously proposed log-periodic power law model of the ``anti-bubble'' regime of the USA market since the summer of 2000, in terms of the renormalization group framework to model critical points. Using a previous work by Gluzman and Sornette (2002) on the classification of the class of Weierstrass-like functions, we show that the five crashes that occurred since August 2000 can be accurately modelled by this approach, in a fully consistent way with ...

[texts]Evidence of a Worldwide Stock Market Log-Periodic Anti-Bubble Since Mid-2000 - W. -X. Zhou
Following our previous investigation of the USA Standard and Poor index anti-bubble that started in August 2000, we analyze thirty eight world stock market indices and identify 21 anti-bubble. An ``anti-bubble'' is defined as a self-fulfilling decreasing price created by positive price-to-price feedbacks feeding overall pessimism and negative market sentiment further strengthened by inter-personal interactions...

[texts]The US 2000-2002 Market Descent: How Much Longer and Deeper? - D. Sornette
A remarkable similarity in the behavior of the US S&P500 index from 1996 to August 2002 and of the Japanese Nikkei index from 1985 to 1992 (11 years shift) is presented, with particular emphasis on the structure of the bearish phases. Extending a previous analysis of Johansen and Sornette [1999, 2000] on the Nikkei index ``anti-bubble'' based on a theory of cooperative herding and imitation working both in bullish as well as in bearish regimes, we demonstrate the existence of a clear signature o...

[texts]Non-parametric Determination of Real-Time Lag Structure between Two Time Series: the "Optimal Thermal Causal Path" Method - D. Sornette
We introduce a novel non-parametric methodology to test for the dynamical time evolution of the lag-lead structure between two arbitrary time series. The method consists in constructing a distance matrix based on the matching of all sample data pairs between the two time series. Then, the lag-lead structure is searched as the optimal path in the distance matrix landscape that minimizes the total mismatch between the two time series, and that obeys a one-to-one causal matching condition...

[texts]Causal Slaving of the U.S. Treasury Bond Yield Antibubble by the Stock Market Antibubble of August 2000 - W. -X. Zhou
Using the descriptive method of log-periodic power laws (LPPL) based on a theory of behavioral herding, we use a battery of parametric and non-parametric tests to demonstrate the existence of an antibubble in the yields with maturities larger than 1 year since October 2000. The concept of ``antibubble'' describes the existence of a specific LPPL pattern that is thought to reflect collective herding effects...

[texts]Numerical investigations of discrete scale invariance in fractals and multifractal measures - W. -X. Zhou
Fractals and multifractals and their associated scaling laws provide a quantification of the complexity of a variety of scale invariant complex systems. Here, we focus on lattice multifractals which exhibit complex exponents associated with observable log-periodicity. We perform detailed numerical analyses of lattice multifractals and explain the origin of three different scaling regions found in the moments...

[texts]2000-2003 Real Estate Bubble in the UK but not in the USA - W. -X. Zhou
In the aftermath of the burst of the ``new economy'' bubble in 2000, the Federal Reserve aggressively reduced short-term rates yields in less than two years from 6.5% to 1.25% in an attempt to coax forth a stronger recovery of the US economy. But, there is growing apprehension that this is creating a new bubble in real estate, as strong housing demand is fuelled by historically low mortgage rates. Are we going from Charybdis to Scylla? This question is all the more excruciating at a time when ma...

An integrable theory is developed for the perturbation equations engendered from small disturbances of solutions. It includes various integrable properties of the perturbation equations: hereditary recursion operators, master symmetries, linear representations (Lax and zero curvature representations) and Hamiltonian structures etc. and provides us a method to generate hereditary operators, Hamiltonian operators and symplectic operators starting from the known ones...

[texts]Evidence of Fueling of the 2000 New Economy Bubble by Foreign Capital Inflow: Implications for the Future of the US Economy and its Stock Market - D. Sornette
Previous analyses of a large ensemble of stock markets have demonstrated that a log-periodic power law (LPPL) behavior of the prices constitutes a qualifying signature of speculative bubbles that often land with a crash. We detect such a LPPL signature in the foreign capital inflow during the bubble on the US markets culminating in March 2000. We detect a weak synchronization and lag with the NASDAQ 100 LPPL pattern...

[texts]Antibubble and Prediction of China's stock market and Real-Estate - W. -X. Zhou
We document a well-developed log-periodic power-law antibubble in China's stock market, which started in August 2001. We argue that the current stock market antibubble is sustained by a contemporary active unsustainable real-estate bubble in China. The characteristic parameters of the antibubble have exhibited remarkable stability over one year (Oct. 2002-Oct. 2003). Many tests, including predictability over different horizons and time periods, confirm the high significance of the antibubble det...

[texts]Testing the Stability of the 2000-2003 US Stock Market "Antibubble" - W. -X. Zhou
Since August 2000, the stock market in the USA as well as most other western markets have depreciated almost in synchrony according to complex patterns of drops and local rebounds. In \cite{SZ02QF}, we have proposed to describe this phenomenon using the concept of a log-periodic power law (LPPL) antibubble, characterizing behavioral herding between investors leading to a competition between positive and negative feedbacks in the pricing process...

[texts]Bubble, Critical Zone and the Crash of Royal Ahold - G. Broekstra
Our analysis of financial data, in terms of super-exponential growth, suggests that the seed of the 2002/03 crisis of the Dutch supermarket giant AHOLD was planted in 1996. It became quite visible in 1999 when the post-bubble destabilization regime was well-developed and acted as the precursor of an inevitable collapse fueled by raising expectations of investors to maintain strong herding pressures...

Experiments have been proposed to verify the effect in a two dimensional electron gas and an atomically flat surface by spin polarized scanning probe microscopy...

First, we develop a simple variant of the canonical averaging method using a rephasing scheme between different samples based on pairwise correlations that confirms Zhou and Sornette's previous results...

[texts]Finite-Time Singularity Signature of Hyperinflation - D. Sornette
We present a novel analysis extending the recent work of Mizuno et al.

On the basis of a generalization of Cagan's model of inflation based on the mechanism of ``inflationary expectation'' or positive feedbacks between realized growth rate and people's expected growth rate, we find that hyperinflatio...

[texts]Zener Transitions Between Dissipative Bloch Bands - Xian-Geng Zhao
Within a two-band tight binding model, we investigate the dynamics of electrons with Markoffian dephasing under the influence of static electric fields. With the help of both numerical and analytic calculations we find that the dephasing ultimately takes electrons which are initially located in one miniband to equal population of the two minibands, instead of undergoing persistent Rabi flop, as they do in the absence of scattering...
[texts]A remark on the local density approximation with the gradient corrections and the X$_α$ method - Y. -B. Xie
We report that the solids with narrow valence bands cannot be described by the local density approximation with the gradient corrections in the density functional theory as well as the X$_\alpha$ method. In particular, in the case of completely filled valence bands, the work function is significantly underestimated by these methods for such types of solids. Also, we figured out that these deficiencies cannot be cured by the self-interaction-corrected-local-density-approximation method.

[texts]Graded Symmetry Algebras of Time-Dependent Evolution Equations and Application to the Modified KP equations - W. X. Ma
By starting from known graded Lie algebras, including Virasoro algebras, new kinds of time-dependent evolution equations are found possessing graded symmetry algebras. The modified KP equations are taken as an illustrative example: new modified KP equations with $m$ arbitrary time-dependent coefficients are obtained possessing symmetries involving $m$ arbitrary functions of time. A particular graded symmetry algebra for the modified KP equations is derived in this connection homomorphic to the V...

Competition effect between dynamic localization and photon-assisted transport has also been discussed.

We study the cross-correlation matrix $C_{ij}$ of inventory variations of the most active individual and institutional investors in an emerging market to understand the dynamics of inventory variations. We find that the distribution of cross-correlation coefficient $C_{ij}$ has a power-law form in the bulk followed by exponential tails and there are more positive coefficients than negative ones. In addition, it is more possible that two individuals or two institutions have stronger inventory var...

The Aharonov-Bohm (AB) interference patterns in ring-shaped conductors are usually dominated by random features. The amplitude of the oscillations is random from sample to sample and from point to point on the magnetic field axis owing to random scattering of the electron trajectories by impurities within the wires. We report experiments on new devices made with wet etching and global gates, which have shown major progress towards removing the random features...

We study trade-based manipulation of stock prices from the perspective of complex trading networks constructed by using detailed information of trades. A stock trading network consists of nodes and directed links, where every trader is a node and a link is formed from one trader to the other if the former sells shares to the latter. Specifically, three abnormal network motifs are investigated, which are found to be formed by a few traders, implying potential intention of price manipulation...

[texts]Dipolar effect in coherent spin mixing of two atoms in a single optical lattice site - B. Sun
We show that atomic dipolar effects are detectable in the system that recently demonstrated two-atom coherent spin dynamics within individual lattice sites of a Mott state. Based on a two-state approximation for the two-atom internal states and relying on a variational approach, we have estimated the spin dipolar effect. Despite the absolute weakness of the dipole-dipole interaction, it is shown that it leads to experimentally observable effects in the spin mixing dynamics.

The scaling functions can also describe data from BRAHMS for both proton and anti-proton spectra at $y=2.2$ and 3.2...

Graded Lie algebras, especially Virasoro algebras, are used to construct nonlinear variable-coefficient evolution equations, both in 1+1 dimensions and in 2+1 dimensions, which possess higher-degree polynomial-in-time dependent symmetries. The theory also provides a kind of new realisation of graded Lie algebras...

We test the Gerasimov-Drell-Hearn (GDH) sum rule numerically by calculating the total photon absorption cross sections $\sigma_{1/2}$ and $\sigma_{3/2}$ on the nucleon via photon excitation of baryon resonances in the constituent quark model. A total of seventeen, low-lying, non-strange baryon resonances are included in this calculation. The transverse and longitudinal interference cross section, $\sigma_{1/2}^{TL}$, is found to play an important role in the study of the $Q^2$ variation of the s...

Here, we combine data on human grouping in a comprehensive and systematic study...

Trigger efficiencies at BES III were determined for both the J/psi and psi' data taking of 2009. Both dedicated runs and physics datasets are used; efficiencies are presented for Bhabha-scattering events, generic hadronic decay events involving charged tracks, dimuon events and psi' -> pi+pi-J/psi, J/psi -> l+l- events (l an electron or muon). The efficiencies are found to lie well above 99% for all relevant physics cases, thus fulfilling the BES III design specifications.

[texts]Manipulating vortex motion by thermal and Lorentz force in high temperature superconductors - Z. Wang
By using thermal and Lorentz force, the vortex motion is successfully manipulated in the mixed state of underdoped La$_{2 - x}$Sr$_{x}$CuO$_{4}$ single crystals and optimally doped YBa$_{2}$Cu$_{3}$O$_{7 - \delta}$ thin films. A conclusion is drawn that the strong Nernst signal above $T_{c}$ is induced by vortex motion. In the normal state, in order to reduce the dissipative contribution from the quasiparticle scattering and enhance the signal due to the possible vortex motion, a new measurement...
